Are Yukon Gold potatoes good for crispy roasting?

Yes. Yukon Golds are all-purpose potatoes with moderate starch, so they crisp reasonably well while staying creamy inside. They are more forgiving than Russets and less likely to fall apart, making them a good everyday choice for roasting.

Why do my roasted potatoes turn out soggy even with a starchy variety?

Sogginess usually comes from overcrowding the pan, which traps steam, or from not drying the potatoes well after parboiling. Even a high-starch potato will steam instead of crisp if it sits in a crowded, moist environment. Use a single layer and pat the pieces dry before oiling.

Can I mix different potato varieties in one roast?

You can, but they will cook at different rates. Starchy potatoes crisp faster and may break, while waxy ones take longer to brown. If you mix them, cut the waxy ones smaller and roast at a high temperature, or accept that some pieces will be softer than others.

What is the best potato for roast potatoes in the UK?

Maris Piper is the traditional UK choice for roasting because it is high in starch but holds its shape better than a Russet. King Edward is another popular option with a fluffy texture that crisps well. Both are widely available in British supermarkets.

Best Potatoes for Roasting Crispy: A Variety-by-Variety Texture Guide

What Makes a Potato Roast Crispy

The crispness of roasted potatoes depends less on the recipe and more on the potato's internal structure. Two factors matter most: starch content and moisture. High-starch potatoes have a dry, mealy interior that absorbs oil well and develops a brittle crust. Waxy potatoes hold more water and sugar, so they steam from within instead of crisping on the surface.

The skin also plays a role. Thicker skins crisp up like a shell, while thin skins can become leathery. For the best texture, you want a potato that can go golden and crunchy on the outside while staying fluffy inside. That balance is easiest to find in specific varieties, which is why the choice of potato matters more than the roasting temperature.

This guide compares the most common supermarket and farmers' market varieties, then walks through a side-by-side roast so you can see the differences in practice. If you are troubleshooting soggy results, the variety you use may be the reason your usual method is not working.

Several types of raw potatoes arranged on a wooden table

Starchy Varieties: Russet, Idaho, and Maris Piper

Russet and Idaho potatoes are the classic high-starch choices. Their flesh is dry and floury, which means they release steam quickly and soak up fat readily. When cut into chunks and roasted, they develop a thick, shattery crust that gives way to a light, fluffy interior. The trade-off is that they can fall apart if you stir them too aggressively or overcook them.

Maris Piper, the British roasting standard, is similarly high in starch but slightly more robust. It holds its shape a little better than a Russet while still delivering a crispy exterior. If you want the crispiest possible result and do not mind some broken edges, Russet or Maris Piper are your best bets. Just be gentle when turning them.

One thing to watch with starchy potatoes is their tendency to absorb oil unevenly. Tossing them in a generous amount of hot oil, rather than drizzling cold oil, helps create an even crust. Parboiling them first also improves crispness, as it softens the surface and allows the exterior to become rough and craggy.

Best for: maximum crunch, fluffy interiors, classic roast potatoes
Crispiness: very high, but pieces may break
Ideal prep: parboil, then roast in hot oil

Waxy Varieties: Red, New, and Fingerling Potatoes

Waxy potatoes like Red Bliss, new potatoes, and fingerlings have low starch and high moisture. Their cells hold together firmly, so they do not fluff up or absorb much oil. When roasted, they brown on the outside but stay dense and creamy inside. The crust is thin and tender, not shattery, and it can turn chewy if the potatoes steam in a crowded pan.

These varieties are a good choice if you want potatoes that keep their shape in a salad or a traybake with other vegetables. They are also less likely to go soggy from excess moisture, because their waxy flesh does not release as much steam. However, they will never reach the same level of crackling crispness as a starchy potato.

To improve crispness with waxy potatoes, cut them smaller so more surface area is exposed, and roast at a high temperature with minimal crowding. A light coating of cornstarch before roasting can also help absorb surface moisture and encourage browning.

Best for: holding shape, creamy texture, mixed roasts
Crispiness: moderate, more brown than crunchy
Ideal prep: cut small, toss with cornstarch, roast at high heat

All-Purpose Varieties: Yukon Gold and White Potatoes

Yukon Gold and other all-purpose potatoes sit between starchy and waxy. They have enough starch to crisp up nicely, but enough moisture to stay creamy and hold their shape. The result is a golden, moderately crunchy exterior with a buttery, tender interior. This makes them the most forgiving choice for roasting, especially if you are cooking a mix of potato sizes.

White potatoes, such as the standard white round variety, behave similarly. They crisp well without falling apart, and their thin skins do not interfere with the crust. If you are unsure which potato to use, an all-purpose variety is the safest pick because it performs well under most roasting methods.

One drawback is that all-purpose potatoes rarely reach the extreme crispness of a Russet. The crust is thinner and less shattery, but it is still satisfying. For many cooks, this balanced texture is actually preferable, especially if you plan to serve the potatoes alongside a juicy roast or gravy that might soften a thinner crust.

Side-by-Side Roast: A Worked Example

To see the differences clearly, roast three varieties in the same oven at the same time. Take one Russet, one Yukon Gold, and one Red potato. Cut each into equal 1.5-inch chunks, leaving the skin on. Parboil all three together for 8 minutes in salted water, drain, and shake them in the colander to rough up the edges. Toss with 2 tablespoons of olive oil and a pinch of salt, then spread them on a single baking sheet.

Roast at 425°F (220°C) for 30 minutes, then flip and roast another 15 to 20 minutes until deeply golden. When you taste them, the Russet will have a hard, crunchy shell and a fluffy, dry interior. The Yukon Gold will be crisp on the outside but creamier inside, with a thinner crust. The Red potato will be the least crunchy, with a dense, smooth flesh and only a light browning.

This example shows why the recipe alone cannot guarantee crispness. If you used only Red potatoes, you might think your oven was too cool or your oil was too little. The variety is the variable that changes the outcome. For a dinner where crispness is the priority, choose starchy or all-purpose; for a salad or a dish where shape matters, choose waxy.

Variety	Crispness	Interior	Best use
Russet	Very high, shattery	Fluffy, dry	Classic roast potatoes
Yukon Gold	Moderate to high	Creamy, buttery	All-purpose roasting
Red	Low to moderate	Dense, smooth	Salads, traybakes

Choosing by Cooking Method and Occasion

Your roasting method can shift which variety works best. If you parboil before roasting, starchy potatoes benefit the most because the pre-cooking softens their exterior and creates more surface area for crispness. If you skip parboiling and roast raw, all-purpose varieties are more reliable, as they do not dry out as quickly.

For a Sunday roast with gravy, a Russet or Maris Piper gives the dramatic crunch that soaks up juices without going limp. For a weeknight sheet-pan dinner with chicken and vegetables, Yukon Golds hold their own and do not need special attention. For a picnic potato salad that happens to be roasted, red or fingerling potatoes are the right call.

The occasion also matters for presentation. Starchy potatoes can look ragged after roasting, which some people love and others find messy. If you want neat, uniform pieces, choose waxy or all-purpose. If you want maximum texture and do not mind irregularity, go starchy.
